    Brembo brake upgrade

    As the title says, I`m in the process of upgrade the front calipers on my 850.

    I got a set of brembo cheap off of ebay and a set of 320mm disc from partsforvolvos.



    A disc was fitted so a caliper could be put over on and measured up for a bracket.
    A alloy one was made for mock up so the fit could be checked and the length of brake hose mesured.
    I needed to use a 5mm wheel spacer to get a volan over the calipers





    Just need to go to my local machine shop a get the caliper carriers made.

    Nice job when it's fitted what is the offset of the Volans ,looks Like discs are a tad big or is it the calipers not on all the way.

    I don`t no the offset of the volans is.

    There`s about 10mm clearance between the caliper and the wheel.

    I dropped into the machine shop with the drawing for the carriers.

    They are a bit snowed under at the moment but should have them made in the next week or two

    I`ve been making the most of this good weather and sprayed my calipers.





    Heard back from the machine shop about the carriers and should be finished next week

    What about brake balance/bias & how do you know these will work with the available master cylinder volume?

    The brake bais will be talen care of by the ABS
    The master cylinder pushes out a set volume of brake fuild which acts against the piston in the caliper, if the caliper has more piston than this volume will than push against these pistons increasing the braking force.

    Yes but if your caliper volume is different then you will not exert the same force as before. This is more of a problem if the new caliper volume is higher than the OEM setup. This will also affect brake bias - front to back. I am concerned that just wacking this on will adversely affect your braking. ABS is controls cadence braking not the available pedal travel, bias or MC volume AFAIK.

    Scary!

    I hope this helps.. I believe in most cases the effectiveness of the calipers will out way the extra travel.
    Also a four pot caliper may actually travel less as the single Volvo piston is doing the work of two by the equal oppostie forces applied to create the clamping force on each side.

    With a small amount of maths you could work it out.We just need the piston sizes of both units and distance of travel required.

    easiest way to compare the volume would be to fill each with fluid and tip it out & measure. The master cylinder when activated wil push the same volume so what you have to be sure of is that overall volume moved by the pedal travel remains the same. I would also measure the diameter of the pistons, as you need to ensure that the push created will work properly too.

    Main difference between your setup and the AP kit is that the AP will have taken this into consideration. the development work is what pushes the price up.

    I am not casting aspertions on your work - making the carriers & all that is commendable.
